b. 250

composition: Op. 49, Fantaisie in F minor

c2 & e2 in A (#→GE) & FE2 (→EE)

b1 & c2 in FE1

..

FE2 restored – perhaps at Chopin's request – the version of the bottom notes of the first two quavers as it was in A, which is an argument that the FE1 text is almost certainly a double mistake by the engraver.

b. 250

composition: Op. 49, Fantaisie in F minor

..

In A and FE there is no accidental to the bottom note of the 7th quaver. One pedal for the entire 2nd half of the bar proves that Chopin heard here one chord, with g. The overlooked  was added in GE and EE.

b. 250-253

composition: (Op. 4), Sonata in C minor, Mvt IV

..

In A there are no accidentals to the 1st quaver in bar 250 and 253. In the main text we add cautionary flats, necessary in this context. In bar 250 a flat was also added in GE (→FE,EE,IE).

Hairpins in EE

Our suggestion

..

Differences in the extent of dynamic hairpins in bars 252-257 and 260-265 may at least partly result from inaccuracies. We adopt the version of FE as our main text, with some modifications in bars 253-254 and 261-262, as shortening of  marks there may have been caused by ends of systems that fell between those bars in FE  (the hairpin is longer wherever the relevant bar - such as 245 – is not at the end of the system).
